How does Wendell Berry use imagery in The Memory of Old Jack?

Example of Imagery:

Jack knew Ben Feltner nearly forty years, and he never saw him in a hurry, and he never saw him angry. With Ben that never seemed merely the result of self-control, but rather of an abiding peace that he had made—or maybe a peace that had been born in him—with himself and the world, a willingness to live within the limits of his own fate. Both of them having grown up in his gentle shadow, Jack and Mat have respected and stood in awe of the deep peaceableness they knew in Ben, both of them having failed of it, and at great cost, for so long.
